Mega D-3 5000 IU & MK-7 180 mcg supplies nutrients that support normal bone and mineral balance. Its identified MK-7 and low serving cost support its appeal.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality70

The identified MK-7 is a favorable vitamin K form. Vitamin D’s source is named, but there is not enough information for a comparative quality judgment.

Ingredient Transparency100

Both nutrient amounts and their forms or sources are disclosed. That makes the combination easier to compare with other D and K supplements.

Value For Money70

The serving cost is low for the MK-7 supplied. Vitamin D’s value cannot be judged separately with confidence.

Customer Satisfaction97

Customer ratings are very positive. The large number of ratings offers a broad view of sentiment, without proving effectiveness.

Product Focus80

The clearest purpose is nutritional support for bone and mineral balance. Findings for artery flexibility are limited to particular groups, and an extra benefit from combining D and K is not established.

Vitamin D and vitamin K supply nutrients relevant to bone and mineral balance, with their value depending on low intake rather than added benefit above adequate intake. The supplied information does not establish extra benefit from combining them or from the MenaQ7 form. Calcium is claimed in the stored label text, but its presence and amount remain unconfirmed and it was not counted.

Vitamin K · 180 mcgVitamin D · 125 mcg

Vitamin D supports calcium absorption and normal mineralization when intake or status is low. The identified MK-7 provides a connection to limited bone-density findings in postmenopausal women at 180 mcg daily, although results are mixed and fracture prevention is unestablished. The high vitamin D serving does not prove greater benefit. Calcium presence and amount remain unresolved despite the supplied label claim, limiting the partner finding.

How this product is rated for Bone Health

Ingredient fit94

Vitamin K is a key ingredient in the saved bone-related findings. The amount criteria are met.
Goal fit
Vitamin K gives the formula a focused bone-related connection, although the product has other linked uses.
Dose adequacy
The credited amounts meet the saved comparison criteria; higher intake does not establish better bone outcomes.

Pathways80

Coverage is strongest for calcium absorption and regulation. The breadth finding includes calcium absorption and regulation, activation of bone proteins.
Depth
The strongest saved coverage concerns calcium absorption and regulation; coverage does not establish a change in bone density or fracture risk.
Breadth
The routes meeting the breadth criterion are calcium absorption and regulation, activation of bone proteins. Other bone functions receive less or no coverage.

Evidence98

MK-7 has limited, mixed bone-density evidence in postmenopausal women; fracture prevention and broader population benefits are unestablished.
Evidence strength
MK-7 has limited, mixed bone-density evidence in postmenopausal women; fracture prevention and broader population benefits are unestablished.
Studied preparation
The credited preparations meet the saved criteria, while the supplied nutritional, population and outcome limitations still apply.

Formulation logic92

The saved findings identify an unmet partner requirement for vitamin d; its contribution is retained with that limitation. No evaluated ingredient conflict was identified.

Vitamin K · 180 mcgVitamin D · 125 mcg

Vitamin K as the declared MenaQ7 MK-7 preparation has limited support for arterial-stiffness changes in healthy postmenopausal women. The 180 mcg serving receives full saved amount recognition, without establishing cardiovascular-event prevention. Vitamin D’s 125 mcg serving also receives saved amount credit, but supplementation has not demonstrated routine cardiovascular prevention, and no additional benefit from combining D and K is established.

How this product is rated for Heart Health

Ingredient fit94

MK-7 provides the main relevant connection. The counted amounts receive full recognition in the saved comparison.
Goal fit
MK-7 gives this product a focused connection to heart-related functions, though it is also linked to other goals.
Dose adequacy
The counted ingredients receive full amount recognition in the saved comparison; this does not establish a proven effective dose.

Pathways60

The saved findings concentrate on the MK-7 arterial-stiffness category. Other pathways do not reach the breadth threshold.
Depth
The strongest saved contribution is in the MK-7 arterial-stiffness category.
Breadth
Only the MK-7 arterial-stiffness category reaches the saved breadth threshold; the findings remain concentrated in that area.

Evidence77

MK-7 leads the evidence comparison, with limited arterial-stiffness findings in healthy postmenopausal women. The saved preparation finding recognizes the counted preparations.
Evidence strength

Formulation logic100

Partner requirements are satisfied and the counted ingredients meet the saved minimum amount comparison. No configured ingredient conflict was matched in the supplied facts.
Partner coverage
The counted ingredients have no unmet partner requirement in the saved findings; this does not imply extra benefit from combining them.

Vitamin K · 180 mcgVitamin D · 125 mcg

MenaQ7 vitamin K2 has narrow findings for selected arterial-stiffness measures in postmenopausal women after three years of use. The 180 mcg serving matches the daily study amount. Vitamin D can support muscle function when deficiency is corrected, but the larger amount here does not imply greater benefit in replete adults or an added benefit from combining D3 with K2.

How this product is rated for Longevity

Ingredient fit94

The formula's focus and amounts produce a relatively close fit with the saved ingredient references. The overall roles remain bounded by the specific evidence for this product.
Goal fit
The relevant ingredients are concentrated on this goal, although links to other uses affect its focus.
Dose adequacy
The recognized amounts closely match the saved amount references; this does not establish additional benefit above nutritional adequacy.

Pathways60

The saved findings are strongest for arterial calcification control, with limited breadth across the other aging-related processes.
Depth
The strongest saved finding concerns arterial calcification control; this describes ingredient roles rather than a demonstrated slowing of aging.
Breadth
Only one pathway reaches the saved coverage threshold, leaving the formula's recognized reach narrow.

Evidence83

Vitamin D drives the leading saved evidence finding. The ingredient-specific limitations above still restrict which practical benefits can be expected.
Evidence strength
Vitamin D supplies the leading saved evidence finding, but its specific population and outcome limitations still apply.
Studied preparation
The saved findings recognize preparation matches for the qualifying ingredients; this does not extend their evidence to broader aging outcomes.

Formulation logic100

The saved formulation findings identify no matched conflicts and no missing required partners. Amount limitations are retained in the individual findings.
Partner coverage
The recognized ingredients either work independently or have their required partner; no extra combination benefit is established.
Conflicts
No matched ingredient conflict was recorded in the supplied calculation.
Effective doses
All recognized ingredients meet the saved amount threshold, which is a calculation reference rather than proof of anti-aging efficacy.

Vitamin K · 180 mcgVitamin D · 125 mcg

Vitamin K as MK-7 has limited evidence for improving selected measures of arterial stiffness in postmenopausal women. This serving supplies 180 mcg, matching the daily amount in the supplied three-year trial. Those marker changes do not establish prevention of cardiovascular events, and vitamin D does not establish an added cardiovascular effect or D3/K2 synergy.
